• Fun with DSP Experimenting programming DSP to a dsPIC chip.

• JDSCA A program to demodulate and decode DSCA.

• JAERO A program to demodulate and decode Classic Aero satellite communication ACARS.

• FastFIR A library with an easy intferface for performing fast filtering using FIR filters. Band Pass, Band Stop, Low Pass, High Pass etc.

• JMSK A cross platform program that implements a good coherent MSK demodulator

• OQPSK demodulator design and testing Designing and testing a good coherent OQPSK demodulator for the purpose of Aero signals

• J-QAM. A QAM soundcard modem Send Data From A to B Via the Soundcard.

• FM stereo encoder A software-based FM stereo encoder

• SLIP library for Arduino A simple packet communication library for Arduino

• JC2Rec A GUI for speech recording using Codec2

• JDDS a GUI for AD9850 DDS modules Create yourself a sine wave signal generator with a nice GUI for a few dollars

• BPSK and Pi/2-BPSK using a DDS via an Arduino Using an AD9850 DDS module with an Arduino and a PC to produce PSK then looking at the difference between BPSK and Pi/2-BPSK

• A good MSK demodulator made in Matlab Using an AD9850 DDS module with an Arduino and a PC to produce MSK. This is then demodulated with a program written in Matlab. Performance is similar to BPSK but with better spectral rolloff

• AV RS232 Sender Send Audio And Video Over A One-way RS232 Link.
